摘　　要：通过动态法优化了密立根油滴实验,分析油滴在无电场中由静止到向下匀速运动,电场中由向下的匀速运动到静止,由静止到向上匀速运动,整个运动过程中各个运动状态的变化,推导出油滴匀速运动的条件,确定了油滴两次匀速运动的位置选取.提高了密立根油滴实验测量的成功几率,使实验结果更加准确.The Millikan Oil-drop Experiment has been optimized through dynamic method.Within the no electric field,oil-drops have different types of motoring conditions,such as from motionless to uniform motion that towards downwards,from uniform motion that towards downwards to motionless and from motionless to uniform motion that towards upwards.The analysis of all those conditions have been conducted,through which the condition of processing uniform motion for oil-drop has been derived,the choice of locations for oil-drop＇s two uniform motions has been confirmed,the chance of success for the Millikan Oil-drop Experiment has been improved.Furthermore,the results of this experiment have become more accurate because those three optimizations.
